In addition, it includes warm illustrations and stylish photo plates, has a new cover, and the text is neatly organized.
It will be of great help to elementary, middle, and high school students, as well as general readers who want to fill in their mathematical knowledge, in understanding mathematics more easily and enjoyably.
This is a book that allows you to take a big step closer to mathematics, which still feels distant, and further helps you take a big step into the world of mathematics.

Marcel Proust, author of the novel In Search of Lost Time, said, “The real voyage of discovery consists not in seeking new landscapes but in traveling with new eyes.”
I hope this book will serve as a guide to help you explore the world through the eyes of mathematics.

In Gulliver's Travels, one foot in Lilliput is equivalent to one inch in Gulliver.
However, since 1 foot is 12 inches, Gulliver's height is 12 times the height of a dwarf, and since the body size is a three-dimensional volume, it is 1728 times the cube of 12, and as a result, Gulliver needs to eat for 1728 people.
Of course, this is not a scientifically convincing argument, as the lower your body weight, the more calories you need per unit of weight.

The speed of walking at a comfortable pace is 5-6 km/h, and the speed of a car in the city is about 40-50 km/h, so the speed of a bicycle is somewhere in between the speed of a human walk and the speed of a car.
Walking allows you to fully savor the slowly changing scenery, while driving allows you to feel the sense of speed. Cycling, both in terms of speed and psychological aspects, is a hybrid that combines walking and driving.

Let's analyze the 2018 professional baseball regular season records using the Pythagorean winning percentage formula.
In Doosan's case, the total points scored are 944, and the total points allowed are 756. If you put this into the winning percentage formula, Doosan's winning percentage becomes 0.6.
However, the actual winning percentage is 0.646, so there is some difference.

Big data, which has recently been attracting attention, is likened to the 'crude oil' of the 21st century.
Just as crude oil is extracted and processed into various products, analyzing big data can help us identify human thought and behavior patterns and create significant value by utilizing them in industries and services.
In the era of big data, statistical techniques for quickly processing massive and complex data are essential, so the importance of statistics is increasing day by day.

There are 25 people on the soccer field: 22 players from each team, 1 referee, and 2 linesmen.
What's the probability that one of these people has the same birthday? It's a staggering 57%.
This is a hard-to-believe result, as it's easy to think that 366 people would have to gather to meet someone with the same birthday, considering that there are 365 days in a year.

Let's find out how the movie "Parasite" was chosen as the winner of the Oscar trophy.
The 2020 Academy Awards winners were decided by 8,469 Academy members, and the selection process was a two-step process.
In the first stage, five candidates are recommended for each category through preliminary voting, and in the second stage, voting is held on the five candidates to ultimately select one.
The second stage is simple because the winner is determined by which film receives the most votes among the nominees, but the first stage is a bit more complicated.

Many soccer fans stay up all night to watch Son Heung-min's spectacular dramatic goal in real time.
The soccer ball that moves dazzlingly and shakes the goal net in accordance with Son Heung-min's footwork is, in geometric terms, a 'truncated icosahedron'.

The magic square can be seen as a symbol of harmony and balance in that each number appears only once and the sum of the up, down, left, right, and diagonals is the same.
Since ancient times, people have longed for a society where all walks of life participate equally and achieve harmony and balance.
Perhaps the reason humanity has been fascinated by magic squares is because they resemble the kind of society we desire.

Graham Moore, who won an Academy Award for his role in The Imitation Game, said at the awards ceremony, “Stay weird, Stay different.”
This is similar to the famous line from Steve Jobs' Stanford University commencement speech: “Stay hungry, stay foolish.”
Turing reincarnated as the Apple Computer logo, and an homage to Steve Jobs's remarks, they're all cool.

Considering that women had limited opportunities to learn mathematics in the past, the existence of female mathematicians who achieved remarkable achievements is all the more significant.
Now that women no longer have to endure the arduous challenges of life to become mathematicians, and that mathematics is no longer a field exclusively for men, I hope to see more and more female mathematicians.

When we experience how close mathematics is to our daily lives, we can recognize the significance and value of why we should learn mathematics.
If you personally experience the value of mathematics like this, wouldn't your heart feel lighter as you embark on the long-distance race called 'studying mathematics'?
